Supergod is the story a British scientist tells of how the world was destroyed by nations putting their trust in hugely powerful beings who can fly. It’s an interesting read for the ideas and the pictures of superbeings reshaping the world.
There aren’t really any characters to get attached to apart from the narrator, who basically takes the place of Uncle Warren telling creepy tales of mushroom sex and soviet robots. Also, because it’s a Warren Ellis comic, of course the British space program plays into the story.
It’s a different take on superhumans than something like Black Summer; a much bigger picture story, and one that highlights how badly people would really deal with that kind of thing.
